The invention relates to a shelf support-combination by meansof which ashelf may be supported upon Vertically disposed side walls. The invention also relates toa combination of supporting side wallsfoack wall, the shelf supporting "a newand novel shelf support combination which is simple its in construction and consequently inexpensive to manufacture and which-effectively supports a shelf.

Another object of the invention is to construct a shelf support combination in which the shelf locks the bracket to the side wall of the shelf support combination.

Another object of the invention is to construct a shelf support combination in which the bracket may be formed from strip material and its finished form completed by a simple punching operation or a punching and bending operation right or the left hand side merely by turning the cabinet upside down. The shelf supporting combination may be utilized in either position of the box with equal efiicacy.

An object of the invention is to provide a shelf support combination which retains the bracket in position upon the side members so that it will not shake loose during transportation or other handling of the cabinet or structure upon which the brackets are mounted.

' Another object is to construct a shelf support and'side wall combination which utilizes a slot in the side wall to support the bracket and means are provided to enclose the slots against infiltrationI-of "dust and dirt which means also serves "the "purpose "of retaining the "shelf bracket in 2 position within the slot when a shelf is not carried by the "bracket.

Qther objects of the invention will be more apparent fromthe following description taken in con ection with the accompanying drawings showing several embodiments of the invention which:

Figure 14 is a horizontal section through the side wall of Figure 11 and showing the shelf support partially advanced towards its final position upon the side wall.

The shelf support combination to be described herein provides a structure for supporting a shelf which is secure and firm yet is easily manipulated for mounting a shelf or the shifting of a shelf to a different level. The simplicity of the shelf support combination also makes it inexpensive to manufacture.

The construction also permits one construction of cabinet to be manufactured which may be used with the hinge means on either side of the cabinet. For example if a cabinet with the door hinged on the right hand side is wanted the cabinet is mounted in that position and if it is desired to have the door hinge means on the left side, the cabinet is merely turned upside down and the shelf support combination is equally effective-and as easily installed or shifted within the cabinet in this reversed position. The one construction of cabinet can be used with equal facility in either position.

The shelf support combination is shown particularly as used in a so-called medicine cabinet mounted in a wall in a bathroom. The cabinet ID has side walls II and I2 and a back I3. A door [4 is mounted upon hinge means 15 on the right-hand side of the cabinet. If it is desired to have the hinge means on the left-hand side, the cabinet only need be turned upside down and reversing the position of the shelf supporting brackets.

Each side wall II and I2 of the cabinet is provided with an inwardly directed channel l9 which because it is inwardly directed furnishes a raised ridge on the inside of the cabinet. The channel or ridge of each side wall has at least one horizontally extending slot therein and preferably a series of such slots are provided in different positions so that the shelf supporting brackets may be placed in any desired level along the side wall or within the cabinet. The slot 20 has a recess 2| preferably on each side of the slot for reasons which will appear more fully hereinafter. The recesses may be located anywhere along the slot depending upon the extent of forward movement of the bracket desired.

A shelf supporting bracket 24 is secured to the side within the slot 2!]. The bracket shown in Figure 3 is made from a flat piece of strip material having parallel sides. A tongue 25 is fashioned at the edge of the strip as by slitting or punching the edge of the bracket inwardly and horizontally or parallel with the edge of the bracket. Preferably a similar tongue is provided upon each side of the bracket so that a bracket may be used interchangeably on either the right or left-hand side of the cabinet. The tongue carries a projection 26 which is preferably struck or pressed outwardly into the tongue and hence is resiliently or yieldably mounted by virtue of the resiliency of the tongue. The tongue or projection also may have an inclined or angular end 2'! to provide a camming surface the purpose of which will appear more fully hereinafter. The projection may be struck downwardly or upwardly as desired.

The forward end of the bracket may carry a shoulder 28. The shoulder serves as a stop for a shelf and also serves to lock the bracket in position on the side wall as will appear hereinafter. In the form illustrated the shoulder is curved so as to receive a curved end or edge of a shelf such as the glass shelf 29. With such arcuate form of shoulder the front edge of the shelf is fixed in position against vertical displacement.

The bracket is mounted on a side wall by slipping the edge of the bracket into the slot 20 with the projection 26 upon the tongue 25 projected through a recess 2! to the other side of the wall of the channel. It will be noted that the projection in the lower face of the bracket requires only the lower recess for insertion of the bracket in the slot, however when the cabinet is turned upside down as previously explained then the recess which heretofore was in the upper position is now in the lower position and passes the projection to the other side of the wall.

The channel is provided for several reasons one of which is to enable a bracket with straight parallel sides to be used. Hence inexpensive strip material may be used for the bracket without machining the side thereof. The edge of the bracket engages the inner surface of the side wall and yet the projection and tongue upon the edge of the bracket is on the other side of the wall within the channel. Preferably the projection or tongue has a width or dimension a little greater than the dimension from the inner face of the side wall H to the outer face 35 of the channel. Actually the inner edge of the projection may be spaced from the edge of the bracket a distance slightly greater than the dimension between the inner face of the side wall and the outer face of the channel. Hence when the 'bracket is moved forwardly in the slot, the camming edge 21 on the projection and tongue resiliently engages the opposite face of the side wall or channel surface so that the bracket is secured within the slot by the projection and the resilient tongue supports it tightly and without shaking.

The channel serves another purpose, in addition to enabling the edges of the bracket to be straight edges and hence can be made from strip material, in that the laterally extending sides 33 thereof at the slot give relatively wide support for the bracket. This support is several times that which would be aiforded by the edges of the slot alone.

The channel serves still another purpose in that the forward laterally extending side of he channel is engaged by the projection 26 which limits the forward movement of the bracket. The channel is made, therefore, with a width and location such that the forward side of the channel is properly located to serve as a stop for the bracket.

If a shelf 29 now has its front end positioned in the semi-circular shoulder 28 of the bracket mounted upon each sidewall and the back edge aliases the pair of brackets, the r "r e ge; of the shelf is closely adjacent or mayfngag the rear wall 13 of the cabinet. Withtheshelf in position it 'will'be observed that the bracket cannot be moved rearwardly because the back edge of the shelf would prevent this movementby engaging the back wall and consequently the brackets are locked in position by the shelf. The back wall of the cabinet serves asses a shoulder 'or abutting means for the rear edge of the shelf which locks the bracket upon the side wall; In the event that the structure is not a cabinet with a back wall which serves asan abutment, suitableabutting means may beprovided at the back end of the side wall to Serve asa stop for the shelf in the same manner that the back wall serves as an abutting means.

A slightly different form of bracket is shown in the upper two brackets of Figure 2 which are also shown in plan View in Figures 5 and 6. The bracket "55 may be used withthe same channel side wall slot and recess. It also may have the shoulder 28. The bracket however uses a pro- 7 jection as which is rigid or non-resilient in that it is struck downwardly at least upon one edge of the bracket and both ends of the projection are integral with the bracket. This projection may have a camming edge3 'l inorder to make it easy to move the bracket to its final position with struction with a rigid projection the resiliency or flexibility in the channel or side wall at the slot is utilized to hold the bracket firmly. v

A different form of bracket is illustrated in Figures 8 and 9. In this construotion the side wall 48 preferably has a channel 4i formed in the side wall which may be either inwardly or outwardly directed, that illustrated being outwardly directed, in order to provide laterally extending edges for greater support or stability for the bracket. The channel in this construction is not essential and serves no other purpose than to supply additional support for the bracket and increase the rigidity of the side wall. The side wall carries at least one and preferably a plurality of horizontal and vertically spaced slots 42 to receive a bracket.

lhe bracket 45 is received in the slots 42 which bracket does not have two straight parallel edges as in the brackets of Figures 2 to 6. This bracket has a projection 46 preferably extending from each side thereof one of which passes through the slot depending upon whether the bracket is used upon a left or right-hand side wall. The forward end of the projection carries a tongue 41 which engages the outer side of the side wall when the bracket is moved forward in the slot. The tongue may be bent inwardly slightly to resiliently engage the side wall and thereby provide a firm support for the bracket. The projection =16 preferably is provided upon each side of the bracket so that it may be used in a left hand side wall or a right-hand side wall. This bracket may have a shoulder 48 at the forward end thereof to engage the front end of a shelf which shoulder serves as a stop for the shelf and the shelf serves to lock the bracket in forward position of the slot and on a suite wall in the same manner that the shelf 45 of Figure 2 serves to lock the brackets upon the side wall. Y

Figure ll) shows a construction in which a relatively deeper channel 5! is provided in the side wall than that illustrated in Figures 1 through 7 and 12 through 14. The channel has a slot 52 and; recess 53 upon each side of the slot. The bracket 56 is received in the slot and 'slidable therein. Because the channel is deeper the bracket needs only one centrally disposed projection 55 which projection may be of the tongue type of Figures 3 and 4 or may be of the rigid type of Figures 5 and 6.

In Figures 11 through 14 'a construction is shown which adds further features to the construction shown in the other figures. The slots extend through the wall of the cabinet and although the shelf bracket or support largely fills the slot there are still spaces which would permit dust and dirt from within the wall to seep through the spaces in the slot into the cabinet. It is desirable therefore to seal or enclose the channel in the side wall which also encloses the slots from communication with the interior walls of the uilding. This seal or enclosure comprises a plate 5S which is secured to the outer face of the side wall at its edge 68 such as by welding. The other edge 6i is a free edge in that it is not Secured but merely rests flatly against the outer face of the side wall. The enclosing plate has a projection 6i which is preferably a ridge extending the full length thereof and forming a locking or retaining ridge. The plate 59 in being secured at one edge only provides a resilient or spring latch in the projection 62 for releasably retaining the shelf bracket against vibrating loose or inadvertent removal from the slot when handled or in transit.

The shelf bracket has an indentation or recess 53 upon each side edge of the bracket and preferably a second indentation (i4 spaced therefrom. The indentation 653 is located in such a position that when the projection 26 of the bracket is inserted through the opening 2|, the plate projection 62 is opposite the indentation B l so that there no resistance to the lateral insertion of the bracket into the slot. When the bracket is moved forward as illustrated in Figure 14 in order to secure the bracket within the slot the slot enclosing plate 55 yields, the indentation having a camming action upon the projection 62. When the bracket has been moved to its forward position, the projection 28 engages the end of the channel and the indentation 6?: comes opposite the projection 62 which snaps thereinto and holds the bracket against inadvertent rearward movement which may release the bracket from the slot. The bracket is therefore removably retained within the slot so that it will not jar loose when the cabinet is in transit or being handled. The plate 59 therefore serves a double purpose in enclosing or sealing the slots from the interior of the wall and in forming a retaining means for the bracket.

The invention is presented to fill a need for improvernents in a shelf support combination and cabinet. It is understood that various modifications in structure, as well as changes in mode of operation, assembly, and manner of use, may and often do occur to those skilled in the art, especially after benefiting from the teachings of an invention. Hence, it will be understood that this disclosure is illustrative of preferred means of embodying the invention in useful form by explaining the construction, operation and advantages thereof.
